Lemierre Syndrome Demonstrating an Atypical Case of Streptococcus Constellatus Causing a Deep Vein Thrombosis in the Left Internal Jugular Vein

Abstract

Lemierre Syndrome (LS) is a rare, potentially life-threatening infection that typically develops from invasion of bacteria through pharyngeal mucosal tissue, followed by septic thrombophlebitis, most often involving the internal jugular vein.1 The primary complication of concern is the formation of septic emboli to the lungs or other organs. Fusobacterium necrophorum is the most common causative pathogen of LS.1 Typically, patients present with high fevers, sore throat, neck pain, and pulmonary symptoms. Though LS diagnosis is often overlooked because the initial manifestations may be subtle and non-specific, prompt diagnosis and treatment with antibiotics are imperative to prevent disease progression and promote quick recovery.
